Radical cations of a soluble rigid tetrathienoacene are capable of forming stable π-dimer dications at ambient temperature when the short backbone becomes extended with conjugated thiophene-2-yl substituents in the α-positions. On the other hand, simple attachment of methyl groups on the α-carbon of the external thiop…
Two new layered transition metal carboxylate frameworks, [Co3(L)2(H2O)6]·2H2O () and [Ni3(L)2(H2O)6]·2H2O () (L = tartronate anion or hydroxymalonic acid), have been synthesized and characterized by X-ray single crystal analysis. Both compounds have similar 2D structures. In both compounds there are two types of metal…
Bismuth potassium titanate, (Bi1/2K1/2)TiO3 (BKT), ceramics were fabricated using smaller-particle-size TiO2 (∼0.1 μm) as a starting material for the improvement of BKT ceramic densification. The BKT ceramics were prepared by a conventional ceramic fabrication process without any additives or special techniques, such…
This work investigates and discusses the thermal, mechanical, thermo-mechanical properties and the morphology of solvent cast products from polylactide (PLA) and polycaprolactone (PCL), as well as their blends containing ethyl cellosolve blocked polyisocyanate (EC-bp), which was introduced as a crosslinker. Differenti…
The behaviors of intrinsic lattice strain and polarization switching under electric fields (E) have been investigated for ferroelectric (Bi0.5Na0.5)TiO3 [BNT] with rhombohedral structure using high-energy synchrotron radiation. Single crystal X-ray diffraction analyses revealed that the lattice parameters exhibited a…
A drag reduction by superhydrophobic (SHPo) surfaces is experimentally confirmed for the first time in a turbulent boundary-layer (TBL) flow, which represents the flows around moving vessels. The drag reduction is measured by comparing the displacement of a SHPo surface with that of a smooth hydrophobic surface in a g…
Based on the fluorescence resonance energy transfer (FRET) and fluorescence anisotropy (FA), the present study reported proof-of-principle for a highly sensitive and rapid detection technique that can be precisely utilized for investigating the self-assembly of polydeoxyadenylic acid (poly(dA)) and β-glucan, and the i…
Although offering superior resistance to corrosion, titanium is unable to withstand discoloration with exposure to peroxide or fluoride. The mechanism of this discoloration, however, remains to be clarified. The purpose of this study was to investigate the mechanism underlying discoloration of titanium with immersion…
We show that the Cauchy--Born model of a single-species 2-lattice is second order if the atomistic and continuum kinematics are connected in a novel way. Our proof uses a generalization to 2-lattices of the point symmetry of Bravais lattices. Moreover, by identifying similar symmetries in multispecies pair interaction…
A novel and facile method is applied to successfully synthesize the 20 mol% neodymium-doped ceria (CNO) nanomaterials, including nanowires and nanoparticles, at 240 °C in ambient air. These special nanostructures are easily densified at 1300 °C and provide a three-dimensional (3D), continuous and fast ionic conduction…
We synthesized pure-silica ZSM-48 zeolite with cheap and conventional amphiphilic organic cation, dodecyltrimethyl ammonium cation, as structure-directing agent. Although severe hydrothermal conditions are usually required to utilize organics possessing anisotropic charge distribution, by controlling the water content…
A unique embossed carbon surface with regionally heterogeneous properties is constructed via carbonization of a polyacrylonitrile-b-poly(methyl methacrylate) (PAN-b-PMMA) block copolymer thin film precursor self-assembled under an external electric field. The PAN-b-PMMA block copolymer generates a thin surface having…
In this paper is given an overall assessment of the condition of the medium voltage XLPE cable population in Denmark. The assessment is based on results from Danish failure statistics. It is concluded that there are no significant signs of an increasing failure rate for dry-cured XLPE cables after a service time of a…
Ultrasmall gadolinium based particles have been functionalized with positively charged pyridinium quaternary ammonium and labelled with (111)In. Evidence of their active targeting properties towards proteoglycans has been demonstrated in vivo after intravenous injection into rats opening thus a route to cancer imaging…
Ferrofluids and dry magnetic particles are two separate classes of magnetic materials with specific niche applications, mainly due to their distinct viscosity and interparticle distances. For practical applications, the stability of these two properties is highly desirable but hard to achieve. Conceptually, a possible…
The interaction of a domain wall (DW) with a propagating spin wave (SW) in soft-magnetic nanostripes is studied analytically. The resonance of the propagating mode with an internal spin excitation of the DW (a Winter-like mode) is examined with relevance to the SW-driven translational motion of the DW. This frequency…
High-temperature CO2 captures using powder and granule is investigated using thermogravimetric analyzer (TGA) and fixed-bed reactor (FBR). The CO2 sorbent, Ca-Al-CO3 powder was prepared using co-precipitation method of Ca+2, Al+3 and CO32- under alkaline conditions. The granule was fabricated by mixing Ca-Al-CO3 powde…
In this work, we prepared multilayered films with repeated Sb and Te layers by a thermal evaporation method. The film structure was controlled by the layer thickness ratio of Sb to Te, resulting in the formation of self-ordered superlattice structured Sb2Te2/Te films and self-ordered Sb2Te3 films. The thermoelectrical…
The sequential reaction of a phosphorus-based trishydrazone ligand, LH3 with anhydrous ZnCl2 and LnCl3·6H2O in a 2 : 2 : 1 stoichiometric ratio in the presence of triethylamine as the base leads to the formation of monocationic trinuclear complexes [L2Zn2Ln]Cl {Ln = Gd (1), Tb (2), Nd (3), Eu (4) and L = [(S)P[N(Me)N=…
